The Difference between PTFE and Expanded PTFE

ePTFE:

 100%virgin PTFE is the material used to produce expanded PTFE.

 ePTFE as a sealing material can be highly compressed.

 It can stand strong against creep and cold flow.

 It can adapt to sealing surfaces easily.

 It can be modified as per requirements such as surface energies, stiffness, hardness, etc.

 It is microporous and so fit for any task that needs airflow.

 It stretches at a high temperature and is smooth in texture.

 It is chemically inactive, water-resistant at low pressure, UV resistant and has a low dielectric constant, radial extension, divergent porosity level.

 It can be used in medical and biological industries, high-performance filters, medical devices, oil and gas industries, electronic insulators, hernia repair, vascular grafts, and other reconstructive surgery, fluidic purification applications, and environmental filtration.

Why Should You Go for an ePTFE over a PTFE?

Both PTFE and ePTFE have superb industrial applications with excellent features. But the range of application of ePTFE is wider than PTFE. The multi-directional fibrous structure of ePTFE makes it capable of performing at a high surface pressure condition. For maximum safety demands like flange sealing of oxygen-carrying tubes, ePTFE is the appropriate material as it can be highly customized. ePTFE has a better performance rate than PTFE. It has so much demand in the market that it is now manufactured with varying heights, densities, and dimensions.
